What is flight?

Flight is when something moves through the air without touching the ground.

Imagine you're on a slide at the park. When you sit down and let go, you zoom down to the bottom, that's like falling. But if you give yourself a little push as you start sliding, maybe even by holding onto the sides and pushing your feet against the slide, you can keep going for longer, maybe even all the way to the end of the park! That extra push helps you stay moving instead of just falling.

Flight works like that push. When something flies, like a bird or an airplane, it uses lift, which is like getting that extra push from the slide. Lift happens because air moves faster over the top of the flying thing than underneath, making it rise up.

Air is important too. It's all around us, when you blow out birthday candles or feel wind on your face, you're touching air. Birds and planes use this air to stay up and move forward, just like you use the slide to keep going.
